Will ´ survive being pasted?
- Normalisation. No. Anything that applies NFKC — search indexes, usernames, domain names, programming identifiers — rewrites ´ as
́. Safe for display, not for storage. - Legacy encodings. ´ exists in Latin-1 and Windows-1252, so even software that predates Unicode can store it.
- Size. 2 bytes in UTF-8. Character-limited fields — SMS, bios, some form validators — usually count bytes, not characters.
Unicode cross-references
The standard points readers of ´ at these characters — usually because they look alike, or because one is the correct choice where the other is often used by mistake.
